摘要: A catalyst for purifying exhaust gas that provides a superior catalytic performance even at a high temperature by increasing the durability of the promoter. The catalyst for purifying exhaust gas includes a promoter clathrate wherein a promoter component particle is covered with a high heat-resistant oxide. A promoter active species is contained in the promoter clathrate. The catalytic active species are located adjacent to the promoter clathrates. The catalytic active species has a precious metallic particle having a catalyst activity, a metallic oxide particle for bearing the precious metallic particle and a metallic oxide placed around the metallic oxide particle and the precious metallic particle.
